The Aradeiba Formation plays a dual role as both a secondary reservoir and an effective seal in the Muglad Rift Basin, deposited in fluvio-deltaic and lacustrine environments. This study focuses on the Aradeiba D-Sand within the Simbir West oilfield, exploring its sedimentology, heterogeneity, and reservoir quality through a multi-scale approach. B...

The Muglad rift basin is a prolific hydrocarbon sedimentary basin. Determining the relations between petrophysical and sedimentological heterogeneity is critical in reservoir studies. This study aims to integrate analyses of petrophysics and rock physics from the Upper Cretaceous Aradeiba, Zarqa, and Ghazal Formations in Muglad basin to evaluate re...

Traditional approaches to fluvial sedimentary analysis often face challenges in deciphering complex, multivariate data-sets. This study combines compositional data analysis (CoDA) with principal component analysis (PCA) to enhance the characterization of depositional processes and sub-environments within the Shendi Formation. The PCA applied to cen...

The Upper Cretaceous Aradeiba and Bentiu Formations are the two main hydrocarbon reservoirs in the Muglad Basin of Sudan. The basin has NW-SE trend and straddles Sudan and South Sudan republics. Following the cessation of South Sudan from the northern part, the Northern Sudan Republic has lost huge oil reserves. However, some northern Sudanese oil...

4D reservoir monitoring has recently become a major tool used to manage the hydrocarbon production of reservoirs. When combined to production well data, high quality 4D seismic is very useful to address production changes in a reservoir over time. This becomes very challenging though, for most of the clastic reservoirs from the J-Area field, in Cen...

Paleozoic, Mesozoic and Cenozoic carbonate ramp successions are excellently exposed in outcrops in central and eastern regions of Saudi Arabia. These carbonate formations are economically important as hydrocarbon reservoir targets in Saudi Arabia and the Arabian Plate in general. During the Phanerozoic time, the Arabian plate passed through various...

Well exposed Jurassic outcrops belt in central Saudi Arabia provides good outcrop analogs which can be utilized to capture the high resolution facies types and architecture that might help to fill the inter-wells gap in the subsurface. This study is focused on the characterization and modeling the facies types, body geometries deposited in geomorph...

The study aims to identify lithofacies, diagenetic properties, porosity and permeability, compressional and shear wave velocity, rock strength and dynamic elastic moduli of carbonate rocks. All these aspects are used together to delineate the major factors that influences acoustic and geomechanical properties of carbonate rocks of Jurassic Dhruma F...

The well-exposed Jurassic carbonate outcrops in central Saudi Arabia provide an excellent opportunity to characterize the detailed microfacies heterogeneity and stratigraphic architecture within the real inter-well spacing. The current study integrates microfacies and stratigraphic analysis of the D5 and D6 Members in outcrops to define lithofacies...

This study characterizes the lithofacies, paleoenvironment and stratigraphic architecture of the D5 and D6 members of carbonates Dhruma Formation outcrops in central Saudi Arabia. The study integrates detailed lithofacies analysis based on vertical and lateral profiles, in addition to thin-sections petrography to reveal the high-resolution architec...

The study aims to characterize the lithofacies, paleoenvironment, high-resolution stratigraphic architecture and reservoir characteristics of Dhruma Formation in outcrops in central Saudi Arabia.

This study investigates the microfacies and sequence stratigraphic frame work of the Middle Jurassic Dhruma Formation in outcrops in central Saudi Arabia. The study contributes to the efforts to understand and enhance local and regional stratigraphic relationship and correlation of the Jurassic carbonate sequences and their significance to reservoi...
